To all whom it may concern:

Be it known that I, CHARLES L. WVA'rsoN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to oil burners of that type in which the oil is atomized by steam generated from water through heat produced by the burner and the object is to produce a burner of this 'type of simple, durable and cheap construction.

71th this general object in view, the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be understood reference is to be had to the accompanying drawing, in which Figure 1, is a top plan view partly broken away of a burner embodying my invention. Fig. 2, is a section of the same on the line II TI of Fig. 1. Fig. 8, is a section taken on the line IIIIII of Fig. 1.

In the said drawing, 1 indicates a pan adapted to rest upon the grate of a cook stove or heating stove or furnace, provided with a plurality of upwardly projecting bosses 2, upon which is supported a box 3 preferably of oblong form if used in cook stoves, the top 4 of the box being preferably secured in place by a plurality of screw bolts 5. The box is provided in its side and end walls near its bottom, with jet orifices 6, and at its front end is provided with a rearwardly facing deflecting plate 7, of bowlshape in cross section, and centrally is provided with a forwardly tapering frustum shaped perforated hub 8, through which a bolt 9 extends to secure the plate in position, said bolt being preferably provided at its inner end with a conical head 10, bearing against said hub 8 and at its outer end the said bolt projects through the front wall of the burner an d is engaged by a nut 11.

12 is an oil supply pipe extending from a suitable source of supply and into the stove, the front wall 8 of which is represented by dotted lines in Fig. 1, and at its upper end within the stove pipe 12 communicates with an arm 13 of a Y-shaped pipe, the stem 14 of said pipe extending rearwardly into the box through the front wall thereof, and the deflector plate 7 and secured upon the inner end of said pipe is a U-shaped nozzle Specification of Letters Patent.

15, arranged to discharge against the head 10 of bolt 9, so that said head in conjunction with the frustum shaped hub shall tend to spread the combustible mixture hereinafter more specifically referred to, in all direc tions in order that it may be Widely disseminated throughout "the interior of the box, and to control the passage of oil which is under pressure, through pipe 12, the latter is provided with a valve 16.

17 is a water supply pipe controlled by a valve 18 and said pipe 17 extends into the stove and communicates at one end with a coil 19, Which coil extends completely around the box in a plane preferably slightly above that of the jet orifices 6, and at its end in front of the box is provided with an upright portion 20, leading to a second convolution 21 of the said coil, the said second convolution being disposed a slight distance above the top of the box and a series of jet orifices 22 therein.

The convolution 21 terminates forward of the box in a return bend 28, communicating with the front branch arm 2-1 of the Y-pipe 1 1-, the arrangement being such that steam generated in the coil, through the impingement thereon of the flame from the jet orifices 6, shall pass into the Y-shaped pipe at an angle to the passage of the oil and thus tend to thoroughly atomize and mix with the oil, which may not be vaporized, from the head of the branch arm 13. The combustible mixture thus produced in the Y-shaped pipe is discharged preferably by a nozzle as hcreinbefore suggested, against the conical head of the bolt to the center of the deflector and is widely disseminated by the latter, in the box and escapes thence through the jet orifices and burns exterior to the box, as hereinbefore suggested.

The preferred way to start the burner is to pour a quantity of oil into the pan 1 and ignite it so that the flame shall raise the box,

the coil, and the Y-shaped pipe to vaporizing temperature. hen this is accomplished the valves are opened to admit water to the coil and oil to the branch arm 13 of the Y-shaped pipe, it being understood that the oil is under such pressure that the steam generated shall not prevent the free passage of the oil into the Y-shaped pipe. I The flame from the burner can be extinguished at any time by closing the valves. Air for the proper support of combustion in the stove may be admitted in any suitable manner, such as by opening a draft damper slightly or a pipe may extend into the stove for the purpose of conducting air to the same.

From the above description it will be apparent that I have produced an oil burner possessing the features of advantage enumerated as desirable in the statement of the object of the invention, and I wish it to be understood that while I have illustrated and described the preferred embodiment of the invention I reserve the right to make all changes properly falling within the spirit and scope of the appended claims.

I claim:

1. An oil burner, comprising a box having jet orifices in its side and end walls, a Y- shaped pipe arranged with its stem projecting into said box, a coil comprising a convolution extending around said box adjacent to the orifices thereof, and a second convolution arranged abovethebox and connected at its discharge end to one branch arm of the Y-shaped pipe, a valve controlled pipe communicating with the receiving end of said coil, and a valve-controlled oil supply pipe connected with the other branch arm of said Y-shaped pipe.

2. An oil burner comprising a box having jet orifices in its side and end walls, a Y- shaped pipe extending into the box and terminating therein in a nozzle, a deflector within the box facing said nozzle, a coil com prising a convolution extending around said box adjacent to the orifices thereof, and a second convolution arranged above the box and connected at its discharge end to one branch arm of the Y-shaped pipe, a valve controlled pipe communicating with the receiving end of said coil, and a valve-controlled oil supply pipe connected with the other branch arm of said Y -shaped pipe.

3. In an oil burner, a box having jet orifices, a Y-shaped pipe extending into the box and terminating within the box in a U- shaped nozzle, a bowl-shaped deflector secured in the box opposite the discharge end of the nozzle and provided centrally with a frustum shaped portion in line with the discharge end of the nozzle, a coil comprising a convolution extending around said box adjacent to the orifices thereof, and a second convolution arranged above the box and connected atits discharge end to one branch arm of the Y-shaped pipe, a valve-controlled pipe communicating with the receiving end of said coil, and a valve-controlled oil supply pipe connected with the other branch arm of said Y-shaped pipe.

In testimony whereof I aifix my signature in the presence of two witnesses.
